Akatin (赤ティン) is an utaite who loves to scream ridiculously and goof around in his covers, often inserting bizarre and humorous dialogue. He is also fond of holding notes for a comically long duration while applying copious amounts of wide and dramatic vibrato.

Akatin is also known for his ability to hit high notes without sounding strained and in some cases, he can even reach a normal woman's vocal range; therefore, he can be called a "ryouseirui". In his less serious covers, he likes to jump into higher and lower octaves and change his voice multiple times in a single song, bellowing at one point to yelling in another.

When his covers are sung (wholly or partly) with a calmer, mid-ranged voice, like in his cover of Donut Hole, he's tagged as "Iketin" (イケティン), which is made up from the words "ikemen" (イケメン) and "Akatin" (赤ティン). Equally, his childish voice is dubbed "Chibitin" (ちびティン).

He often covers songs more than once and sometimes includes passages from other songs in his covers, such as "Souzou Forest" in his cover of "Kisaragi Attention" or "Melt" and "Fire◎Flower" in his cover of "Babylon".
